I have made an appointment to take my iMac into the Apple Store.  It is one of those which needs its Seagate Hard Drive replaced.  I am told I should erase the old drive - I can't imagine they'll give it back to me.  I have Time Machine hooked up. 

 

First question:  how long should it take to do the erasure so I can use my Mac as long as possible before sending it to the vet?  

 

Second question:  I know I will have to reload programs - I upgraded to Lion (online) and I am pretty sure I burned discs at the time.  What about other programs I may have purchased over the internet?  Will they still be tucked away in Time Machine? 

 

Third question:  should I unhook Time Machine before doing the erasure? 

 

How do I start the erasure? 

 

Is there anything else I should be aware of? 

 

Am feeling a bit anxious about this so any advice would be greatly appreciated. 

 

Thanks,

Jaz


iMac, Mac OS X (10.6.7)

    1. The normal erase takes less than a minute, but if you use a secure erase option, it takes more than an hour.

     

    2. You have to contact with the developer if the programs use a serial number.

     

    3. Before erase the disk, make a Time Machine backup and disconnect the disk.

     

    To erase the disk, insert the Mac OS X DVD that came with the Mac and press C key on boot. Then, go to Utilities > Disk Utility, select the hard disk in the sidebar and go to Erase tab. Finally, press Erase and turn off the computer.

     

    When you have your Mac with a new hard disk, you must ask to the Genius if the hard disk has got Mac OS X Snow Leopard installed or if the hard disk is blank. Depending of this, you can restore your backup in Setup Assistant or you'll have to start from the Mac OS X disc to restore the backup. Anyway, when it finishes, open Apple menu > Software Update and update to the most recent version

    for more information. Do note that the program goes to at least 12 APR 13, so there's no hurry to jump in. That gives you time to get all of your ducks in a row before proceeding.

    Many thanks Mende and Baltwo.  I read your posts and explored the discussions and feel much better informed - though far from being expert.  Do you think using a clone program like CCC is worthwhile compared to using Time Machine backup and individual reloading of programs?  The cost of CCC does not appear exorbitant and it looks like it might be a less clunky process. This is the first I have heard of cloning.  I keep two Time Machine discs which I alternate every month or so but will bring both up to date before surgery on the Mac.

    I only use CCC to make bootable clones. They're immediately testable by booting into them. I don't use TM, since I've never had to restore anything I threw away (since starting with computers in the late '50s). The main issue with TM is that it's not bootable and you can only verify its veracity by restoring the TM backup. That requirement and the necessity of having the ext HD attached and running mitigate, IMO, as being a useful solution. If you reply solely on TM, then you've put all of your eggs in one basket. I've multiple clones on multiple HDs, so have no issues relying on them.

     

    As for CCC, I'm biased, since I moderated its previous forums for over six years. It's the only thing I'll ever use.

    Again, thank you.  Makes you wonder why Apple promote Time Machine when it would seem like a better alternative for their customers if they provided a clone program - which I guess would hook up and back up similarly to TM but have the added advantages you mention in your post.

    The advantage of Time Machine is that it makes automatic, acumulative, hourly backups without have to do this manually and copy GBs to an external disk

    Apple did. It was called Backup, but couldn't compete.

    Thanks again.  Will be away from computer for a while.  Will seriously consider CCC.

    The disadvantage of TM is that it requires a large HD (2-3 larger than what it's backing up) to accommodate its cumulative backups, needs to be powered up and connected, and requires restoring to verify its veracity. Automatically scheduled, incremental updating of bootable CCC clones is one of its features. Additionally, the cloning the Recovery HD (Lion and ML) is another.
